(DEDICATED TO THE PUBLIC.)

To all whom it may concern:

Be it known that I, FREDERICK W. STAN- LEY, a citizen of the UnitedStates of America, and an employee of the Department of Agriculture ofthe said United States, residing in the city of Washington, District ofColumbia, (whose post-oltlce address is l Vashington, Districtoit'Columbia,) have invented a new and useful Improvement in AutomaticIrrigation-Nozzles This application is made under the act of March 3,1883, chapter 1&3 (22 Stat., 625), and the invention herein describedand claimed may be used by the Government of the United States, or anyof its oflicers or employees, in the prosecution of work for theGovernment, or any person in the United States, without payment to me ofany royalty thereon.

My invention relates to irrigation nozzles which are'adapted, underwater pressure, automatically to assume various positions.

The object of my invention is to provide an irrigation nozzle simple inconstruction and easy of operation, and one which is specially designedautomatically to assume various positions while spraying a given plot ofground so as to irrigate a large area without moving said nozzle toanother posltion in the field.

The object, characteristic features, and scope of my invention will bemore readily understood from the following description taken inconnection with the accompanying drawing, wherein:

Figure 1 is a perspective view of the nozzle;

Fig. 2 is a longitudinal sectional view, and

Fig. 3 is a side elevation looking toward the ratchet member.

Referring to the drawings,Arepresents a nozzle standard connected with awater main or other convenient source of water supply. A cylinder, B, issecured to the pipe, A, in any suitable manner, or said cylinder mayform an integral part of said pipe. An opening is cut in said pipe andone in said cylinder. These openings are designated C, and are cutopposite each other in said mentioned parts for providing means by whichwater may "pass from the pipe, A, into the cylinder, B, for effectingthe purpose hereinafter specified. Adjusted in said cylinder, B, is aplunger, D, having secured thereto a pist0n rod, E, passing through aspring, F, which is arranged in operative position between said plungerand the top of cylinder B.

To piston rod, E, is connected a second rod, G, which engages thenotches, H, of the ratchet wheel, I, which is conveniently attached bysuitable means to the water supply pipe, A. Guide rods, J, secured tothe pipe, A, serve to keep the rod, G, in proper working position.Nozzle head, K, having a plurality of apertures, L, cut in the upperend, is adjusted to the supply pipe, A, by means of the rod, M, in sucha manner as to allow the nozzle head, K, to assume various positions.Securely attached to the nozzle head, K, is the projection, N, to whichis attached the rod, 0, which in turn is attached to the projection, P,on the ratchet wheel, I.

In practising my invention, the water is admitted under pressure throughthe supply pipe, A. Part of the water will pass through the aperture, G,into the cylinder, B, the pressure being communicated to the plunger, D,(the plunger being down), which pressure serves to raise the plunger, D,carrying with it the piston rod, E, and the rod, The rod, G, engagingthe notches, H,

on being raised, serves to turn the ratchet wheel, I, a short distance.The ratchet wheel, I, is oblong, with the notches, H, shorter in thecenter than near the ends. The rod, 0, being attached to the ratchetwheel, I, by means of the projection, P, and to the nozzle head, K, bymeans of the projection, N, communicates the movement of the ratchetwheel, I, to the nozzle head, K, which tends to cause the nozzle head,K, to take various positions. The water under pressure through the pipe,A, passes through the apertures, L, in the form of a spray. The positionof the nozzle head, K, is constant after the water is once turned on,until the water is momentarily shut off, which shutting off serves torelieve the pressure, which in turn allows the spring, F, to carry theplunger, D, down and allows the rod, G, to engage another notch, H, inthe ratchet wheel, I. The water being again turned on, the pressurethrough the plunger, D, the rod, G, the ratchet wheel, I, and the rod,0, serves to cause the nozzle head, K, to assume a slightly difl'erentposition. The position of the nozzle head, K, can be changed as often asdesired bv momentarily shutting off the Water, which shutting oii andagain turning on cause the position of the nozzle head, K, to assume aslightly different position. The oblong shape of the ratchet Wheel, I,and the diflferent lengths of the notches, H, give slower action Whenthe nozzle head, K, is nearing the perpendicular, thus giving betterdistribution.

It is also claimed that this device can be used to oscillate spray headsof various clesigns, being especially useful for oscillating a long,horizontal pipe that is supported by posts or cables at a convenientheight above the ground. surface, this pipe bearing nozzles atconvenient intervals. In such an irrigation device, spray head, K,bearing small apertures, L, would be replaced by a long pipe that Wouldoscillate about the fixed part, A. The connecting pin, M, would bereplaced by some common form of turning union, and nozzles, K, Would beset 3 to 4 feet apart, the nozzles or apertures throwing streams inparallel lines.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention Will be apparent tothose skilled in the art,Without further description, and it Will beunderstood that various changes in the size, shape, proportion, andminor details of con- Gopies of this patent may be obtained forstruction may be resorted to Without departing from the spirit orsacrificing any of the advantages of the invention.

Having thus described my invention, I claim:

1. In an irrigation device, the combination of a supply pipe, a nozzlemovably con- -nected thereto, a cylinder in communication with saidsupply pipe, a piston in said cylinder, a rod connected to said piston,a ratchet wheel connected to said nozzle and adapted to be engaged bysaid Ted so that movement of the piston is communicated through saidratchet Wheel to said nozzle.

2. In an irrigation device,- a movable nozzl'e, a cylinder, a pistontherein, a supply pipe in communication With said nozzle and saidcylinder, and connections between said nozzle and said piston includinga series of rods and a ratchet Wheel, the piston adapted to be moved byturning on and off the Water to the supply pipe to change the positionof said nozzle.

In testimony whereof,- I aiiiX my signature in the presence of twosubscribing Witnesses.
